    This cadaveric study compared round and flat sutures in interference-fit anchors at the glenoid and greater tuberosity.

  • 2

    The study tested 48 glenoid constructs using three suture types and 30 humeral constructs using five suture-anchor combinations.

    The authors hypothesized that flat tape sutures would have lower suture pullout strength than round sutures because of their compressed geometry beneath the anchors.

  • 4

    Five pairs of cadaveric shoulders were tested; one glenoid pair was excluded because improper storage made it unsuitable.

  • 5

    The study assessed suture pullout at the anchor interface, an area not directly compared between round and flat sutures in prior investigations described by the authors.
